Definitions

  • the present invention/innovation relates to an explosion cover plate, especially an explosion hatch, of the type specified in the preamble of claim 1.
  • Such explosion cover plates may be employed especially in plants where dust explosions have to be expected. Their valve-action is intended to prevent breakage of, or damage to, parts of the plant at undesired locations caused by a certain overpressure.
  • the explosion cover plates constitute the "weakest" parts of the plant or the container or the wall, respectively, so that the over-pressure may be balanced. Accordingly, such explosion cover plates may also be employed in systems where undesirable negative pressures may occur.
  • the invention/innovation resides in that the clamping section is bridged by at least one lever arm one side of which is pivoted to the wall--or to the plate--and the other side thereof is supported by the plate or, respectively, the wall or, respectively, the clamping section when a locking element which in the closure position prevents rotation of the lever arm about the pivot permits rotation of the lever arm about the pivot by breaking upon the occurrence of the predetermined overpressure or, respectively, negative pressure.
  • the holding pressure which retains the plate within the opening in the wall is no longer transmitted only by the sealing member formed as a clamping section and consisting especially of rubber or of a rubber-elastic plastics material. Rather, the lever arm has the function of additionally supporting the plate.
  • an adjusting element particularly with a screw, whose tip or head may be brought into engagement with the outer side of the plate.
  • FIG. 1 is a schematic partial plan view of a hold closed by an explosion hatch
  • FIG. 2 is a side view, partially in cross-section, along the line I--I of FIG. 1;
  • FIG. 3 is a top view--partially broken away--of the area of the lever arm and the corresponding transitional zone from the wall via the clamping section to the plate;
  • FIG. 4 is another embodiment of the invention/innovation according to FIG. 1 and shows a fragmentary portion of the plan view of an explosion door;
  • FIG. 5 is a cross-sectional view of the transitional portion from the wall via the clamping section to the plate, including a side view of a different structure of the lever arm;
  • FIG. 6 is a partial plan view of the pivot of the embodiment of FIG. 5.
  • a loading hatch with an opening of several square meters, which is closed by means of a plate 4 constituting the explosion cover plate according to the invention/innovation, which plate may also be called a "hatch cover".
  • the outer edge of the plate 4 is inserted into a recess of a clamping section 1 the opposite recess of which--as will be apparent especially from FIG. 2--is mounted on the rim 9 of the wall 3 defining the opening.
  • the clamping section 1 forms a sealing member preventing rain or seawater from penetrating into the hold cover by the plate 4.
  • the clamping section 1 retains the plate 4 in the desired position.
  • the plate is also supported by means of a lever arm 2 the left end of which--in FIG. 2--is pivotally secured at the pivot 7 by means of a pin to a U-section bearing block 6 whose web portion is welded to the wall 3.
  • the opposite end of the lever arm 2 is provided with an adjusting element 8 which is constituted by a screw and the free end of which may be brought to bear against the outer side of the plate 4.
  • the distance C between the upper edge of the lever arm 2 and the outer side of the plate 4 may be varied by turning the screw, i.e., the adjusting element 8.
  • the lever arm 2 is additionally connected to the bearing block 6 at a distance A from the pivot 7 by means of a shearing pin serving as a locking element 5.
  • the distance A is e.g. 70 mm while the distance B from the point of engagement of the adjusting element 8 with the plate 4 to the pivot 7 is about 30 cm.
  • the adjusting element 8 may e.g. be a screw provided with a thread M12, while the shearing pin is of aluminum and has a diameter of 6 mm.
  • the bearing block 6 is a U-iron having a thickness of 4 mm and the dimensions 40 ⁇ 50 ⁇ 40 mm.
  • the lever arm 2 also is a U-iron but has the dimensions 40 ⁇ 60 ⁇ 40 mm so that there will be no play on either side between the inner sides of the legs of the lever arm 2 and the outer sides of the legs of the bearing block 6. Therefore the height D of the legs of the bearing block 6 is 40 mm.
  • the distance G from the pivot 7 to the rim 9 of the wall 3 defining the opening is about 12 cm in this embodiment.
  • the lever arm 2 has a width of 60 mm, and the bearing block 6 has a width F of 50 mm.
  • the plate 4 is pivoted to the wall 3 with common links on the left-hand side of the drawing while it is only at the right-hand side that by means of the lever arm 2 and the same structure as in FIG. 1 it will be torn from the locked position into the opening position when a predetermined limit pressure is exceeded.
  • the links 10 ensure that the plate 4 will not be flung away but will remain secured to the wall 3.
  • the bearing block 6 is secured to the lower side of the plate 4 such that the retaining force through the lever arm 2 and the adjusting element 8 can be varied by urging the screw constituting the adjusting element 8 towards the inner side of the wall 3 and increasing the pressure by turning the screw further inwardly.
  • the locking element 5 will break so that the lever arm 2 will be swung counterclockwise and the plate 4 may be torn from the rubber-elastic clamping section 1.
  • the locking element 5 of the embodiment shown in FIGS. 5 and 6 is disposed on the side of the pivot 7 of the lever arm 2 remote from the adjusting element 8. But in this case, too, the torque is determined by the distance A between the pivot 7 and the locking element 5.
  • the ratio of this distance A to the distance B also determines the ratio between the force required for breaking the locking element 5 and the compressive force applied to the plate 4.
  • the distance between the point of contact of the adjusting element 8 on the plate 4 and the locking element 5 or, respectively, the pivot 7 may be made variable.
